Description
Technical field
It relates to for the method and system collecting thermoplastic resin.
Background technology
Along with the use of durable consumer goods is more and more universal, use High performance plastic resin, its kind the most more
Class also will be more, it is therefore desirable to toughness and mouldability according to resin collect these high-performance thermoplastic trees subtly
Fat, for recycling, forms higher-quality thermoplastic resin.Particularly more come in household wares and Automobile Products
Use high performance thermoplastic resin manyly.Especially, when using high property in optical element and high-strength parts
During energy thermoplastic resin, processing technique is extremely complex, and raw material is the most costly；Accordingly, it would be desirable to these are high
The thermoplastic resin of performance can recycle to be more nearly the quality level of the quality level of original product.
The most generally the method collecting thermoplastic resin of employing is by means of proportion and/or charge characteristic, even now
Method is very simple, but is but unsuitable for collecting high performance thermoplastic resin subtly.Such as, because should different
In with, (television set, automobile etc.) expects that high performance thermoplastic resin has different thermostabilitys and mouldability, because of
These needs carry out different adjustment according to different application scenarios, including changing molecular weight, being doped with different molecular weight
Polymer, the different monomer of copolymerization, and add functional group, and in some cases, also can mix different
Polymer, thus form polymer alloy.By such adjustment, can be as required by the organic composite of limited quantity
Thing (monomer) makes the thermoplastic resin of various characteristic.But, such adjustment is without making high-performance thermoplastic tree
Fat has proportion and the charge characteristic of inequality；Therefore, these high-performance heat is collected by proportion and/or charge characteristic
Plastic resin is relatively difficult.
Additionally, in the case of being adjusted according to molecular weight, even if carrying out the spectrum analysis of such as infrared analysis,
It is also impossible to be collected.For copolymer, polymer mixture and polymeric alloy, to a certain extent
Identification in addition can be carried out by spectrum analysis, but hardly possible accurately identification and be collected in thermoplastic resin intermixture
In miscellaneous thermoplastic resin of containing with different weight percentage.
In order to reclaim be more nearly the quality level of original product by quality level in the way of, need to receive more subtly
Collection thermoplastic resin.Specifically, not only will according to title material (such as ABS, cyclenes, polyimides etc.),
But also to collect thermoplastic resin according to the characteristic of their molecular weight and such as thermostability or mouldability.Heat-resisting
Property determined by the material that used, and mouldability is determined by the requirement of product.Poor mouldability can make product have
Flaw, thus the quality of product can be greatly affected.
For thermoplastic resin, directly affecting of the softening point that thermostability is represented by Tg (vitrifying point),
And mouldability is affected by the storage modulus in the temperature range (caoutchouc elasticity scope) from vitrifying point to melting point.
On the whole, such characteristic is normally referred to as rheological behavior (kinetics viscoelasticity).Some thermoplastic resins have phase
As main chain (backbone), thus Tg is of substantially equal, but has different characteristic (examples in the range of caoutchouc elasticity
As, the difference such as storage modulus).Because the purpose being adjusted such thermoplastic resin is primarily to improve it
Mouldability, thus preferably separate these thermoplastic resins, and to by the product with original this thermoplastic resin of use
The thermoplastic resin that as category, the thermoplastic resin of these in product is made is recycled.

The principle collecting thermoplastic resin based on rheological behavior it is described more fully hereinafter with reference to Fig. 5 to Fig. 9.Figure
5 rheological behaviors showing different thermoplastic resin a, b, c and d.Its represent the most respectively temperature and
Pressure.The operation that system 10 according to the disclosure is carried out has uniqueness based on thermoplastic resin a, b, c and d
Rheological behavior.Such as, consider collect have rheological behavior as shown in Figure 5 thermoplastic resin a, b, c and
During d, can be collected by procedure below.
First, as shown in Figure 6, temperature can be set as T1, this temperature T1 is higher than thermoplastic resin a's and b
Tg, but is below the Tg (Tg (a)=Tg (b) < T1 < Tg (c) < Tg (d)) of thermoplastic resin c and d.
Here, Tg (a), Tg (b), Tg (c) and Tg (d) represent thermoplastic resin a, b, c and d respectively
Tg.At temperature T1, only thermoplastic resin a and b enters caoutchouc elasticity state, and their storage modulus
It is about the one thousandth that temperature is storage modulus during Tg or following.Therefore, towards thermoplasticity at temperature T1
During resin a, b, c and d extruded hollow mould 20, only there is areal deformation in thermoplastic resin a and b.
The Stress control can being applied on pressure roller 40 and be set as P1 (r1 (a) < P1 < r1 (b)), it is higher than r1
(a) (=thermoplastic resin a storage modulus E1 (a)/(required strain fm) at temperature T1), and be less than
R1 (b) (=thermoplastic resin b storage modulus E1 (b)/(required strain fm) at temperature T1), wherein
Fm represents being partly at least one hole 22 described and being attached to the surface of hollow mould 20 of thermoplastic resin
Minimum strain required on 21.By identical mould, the thermoplastic resin with known features being carried out process can be true
This value fixed.Storage modulus E2 of thermoplastic resin b is more than E1 (E1 < E2), and P1 < r1 (b) (=thermoplastic resin
Fat b storage modulus E2/ (required strain fm) at temperature T1).Therefore, even at thermoplastic resin b
In the case of contacting with hollow mould 20 under pressure P1, the surface of thermoplastic resin b also will not occur enough
Deformation.Then, hollow mould 20 only captures thermoplastic resin a, thus can be from remaining thermoplastic resin b, c
With d isolates thermoplastic resin a.
Then, as it is shown in fig. 7, in the case of maintaining temperature to be T1, can be by boost in pressure to P2, it is more than r1
(b) (=thermoplastic resin b storage modulus E1 (b)/(required strain fm) at temperature T1), and repeat
Identical process.In the case, in the group of remaining thermoplastic resin b, c and d, only thermoplastic resin
There is sufficiently deformation in b, thus is captured by hollow mould 20.So, can be from remaining thermoplastic resin c and d
In be separately separated out thermoplastic resin b.
Such as, as shown in Figure 8, temperature can be brought up to T2, this value is positioned at Tg (c) and the heat of thermoplastic resin c
Between the Tg (d) of plastic resin d, and pressure is set to P1.At temperature T2, thermoplastic resin c is in
Caoutchouc elasticity state, but r2 (c)=(=thermoplastic resin c storage modulus E2 (c)/(institute at temperature T2
The strain fm needed)) more than P1 (P1 < r2 (c)).Therefore, the surface of thermoplastic resin c does not deforms, therefore
Thermoplastic resin c is not captured by hollow mould 20.
As it is shown in figure 9, owing to pressure being further increased to P2 and having carried out identical operation, thus by r2 (c)
It is set smaller than P2 (r2 (c) < P2).Therefore, there is sufficiently deformation in thermoplastic resin c, and by hollow mould
20 captures.So, thermoplastic resin c can be isolated from remaining thermoplastic resin d.By such operation weight
Change temperature and pressure again, such as, by raising temperature and pressure the most from low to high, can be by their stream
Become characteristic and collect different thermoplastic resin a, b, c and d subtly.
Hereinafter this process is summed up.First design temperature.Then, while maintaining temperature, change step by step
Pressure changeable.Finally, separate and collect rheological behavior thermoplastic resin in given range.Such as, warmed-up heat
The temperature of plastic resin a, b, c and d can be about 35 degrees Celsius to about 200 degrees Celsius.Pressure applied is poor
Can be about 0.01MPa to about 10MPa.Such as, if the one in thermoplastic resin a, b, c and d is glass
Transition point be about from 96 degrees Celsius to about 105 degrees Celsius and its storage modulus at 130 degrees Celsius time be about 5MPa's
ABS resin, then, under 130 degrees Celsius, the pressure reduction being applied in ABS resin is about 1MPa to about 10MPa.
And, if the one in thermoplastic resin a, b, c and d is glass transition point is about 135 degrees Celsius and energy storage mould
Amount is about the cycloolefin copolymer resins of 0.13MPa when 170 degrees Celsius, then, under 170 degrees Celsius, be applied to
Pressure reduction on cycloolefin copolymer resins is about 0.05MPa to about 0.5MPa.

| Temperature | Pressure | Resin in mixture | The resin separated | Remaining resin |
| T1 | P1 | a,b,c,d | a | b,c,d |
| T1 | P2 | b,c,d | b | c,d |
| T2 | P1 | c,d | Non | c,d |
| T2 | P2 | c,d | c | d |
By repeat above procedure, by processing repeatedly above under identical temperature and pressure, can improve by
The purity of the thermoplastic resin of empty mould 20 capture.
